Once you have cygwin32 (with gcc-2.95) and you can get the ant environment variables sorted out using the apache/tomcat combo is a piece of cake.

Re: aaargh!
Horses for courses.. Win98 is designed to run games and Microsoft Office; it's not a webserver platform. Yes, it's possible to build a Unix-like development environment, but it will take work. Most Unix-esque open source stuff can be made to run on some versions of Windows, but it can take work. Conversely, Linux requires some hassle to support MS-Office documents (you have to tell Netscape to launch StarOffice / ABIword / ApplixWare) has limited support for browser plug-ins, and no games to speak of, but has an extremely comprehensive development environment out of the box (gcc, make, emacs, perl, tcl, cvs, ..) and you can build Apache from scratch like this: tar xvzf apache-1.3.19.tar.gz ; cd apache-1.3.19 ; ./configure ; make ; make install I must say I'm slightly surprised that you can't find a pre-built gcc binary for Win98 that you can use without needing to bootstrap via another compiler. I'd seriously suggest partitioning your hard disk and doing your Java servlet tinkering in Linux - you'll find it a lot less stressful. At minimum, can 98 in favour of NT.

RE: aaargh..
Its all of because where your code gets placed. That is, the useBean tag is translated into code which comes before any of the <% %> code in the body of JSP. So when you use setProperty it is transalted into code that comes before your <% %> code but there is no bean at that point. Instead of changing the bean, you could put initialization code inside the useBean tag. <% ...any java code %> This way, the code you include will be placed at the right point when your JSP is turned into a servlet. The setProperty tags will get transalted into code that comes after this. I hope this helps. >just for arguments sake, why does then usebean tag need to create a bean before i can use set- >and getProperty on it? thnx, -Alexander.

Right now this means that cannot create a person because it doesn't know how to give that person a unique id... So you are saying that the usebean tag should create the instance of my person bean? and only after that can i try getProperty and setProperty? This would mean some re-writing of my beans, so something like below WOULD work? ::: add.jsp ::: just for arguments sake, why does then usebean tag need to create a bean before i can use set- and getProperty on it? thnx, -Alexander.

In your useBean tag, did you give the complete package when naming the class?
